By replacing solvent-based adhesives with hot melt adhesives, we contribute to environmental improvement, increased line speed, and enhanced productivity.
Generally used adhesives include solvent-based and water-based adhesives, which cure and bond as the solvent or water evaporates. Many industrial solvent-based adhesives can have harmful effects on human health, and using solvents involves various issues such as employee health management as stipulated by occupational safety and health laws, installation of exhaust systems, storage facilities as required by fire safety laws, and environmental concerns, all of which incur significant costs. At Suntool, we propose hot melt adhesives as a solvent-free alternative, providing numerous benefits to our customers, including improvements in environmental issues and working conditions. We would like to introduce a case where the issue of solvent use was resolved with hot melt adhesives.
